Logic Masters Deutschland e.V.

During a work meeting someone drew a bunch of lines and arrows on the whiteboard, but it looks like they made some mistakes. Can you find all the mistakes?

Rules:
1. Normal Sudoku rules apply. Place the digits 1 - 9 once each in every row, column, and box.

2. ARROWS: Values on arrows sum to the value in the attached bulb.

3. REGION SUM: Box borders divide a blue line into different segments which all have the same sum.

4. RENBAN: Values along a purple line must be consecutive and non-repeating.

5. MISTAKES: There are 9 mistake cells in the grid. One in every row, column, and box, and each containing a different digit. It's up to the solver to find all the mistake cells. The value of a mistake cell is 10 minus the digit in the cell. (For example, if there is a 3 in a mistake cell it's value is 7. Also known as a Mirror Cell.)
